This looks like B. fuscescens to me. But in the end I have to run everything by Trevor. I still regularly get it wrong even when I think it’s obvious.

along with the soralia being larger than the branches they arise from seems to indeed indicate B. fuscesens :) (I can’t seem to get the V vs U thing on some of these specimens, seems kinda variable sometimes).

With soralia…

Best odds are on B. fuscescens. B. glabra is hard to distinguish but also common farther north: it tends to be shinier and its branch axils are sort of rounded and U-shaped. The other one to watch for is B. fremontii, but it should have yellowish soralia, thicker “trunk” branch, and is P- (the other two are P+o/r).
